 fig. 1 1 B) the ventral cord is f oraied by the left vagus, the dorsal 

 cord by the right one, and communications run between the 

 nerves. 



In Felis bengcdensis (text-fig. 4) and Paradoxurus larvatus 

 (text-fig. 6) the ventral cord is a branch of the right vagus and 

 the dorsal cord is a combined trunk of the vagi. In the former

In Procyon lotor (text-fig. 9 B) the ventral and dorsal cords 

 arc produced by both vagi after forming a complex plexus guise. 



In Canis thous (text-fig. 5) both vagi divide. The mesial 

 halves unite to form the ventral cord, and the lateral halves fuse 

 to form a very thick dorsal cord. 



The ventral and dorsal cords end in difi"erent ways in the
